Prices in Sevenoaks
Our South East England guide price for air-to-air heat pumps is £3,595–£13,945 for 2–5 rooms, VAT included. That is above the UK middle, mainly because labour and access cost more in South East England. What moves a quote in Sevenoaks up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. Typical Small home work (three or four rooms heated and cooled) lands around £5,445–£9,095 in this area.
Two rooms
Living room and main bedroom on one outdoor unit.
Small home
Three or four rooms heated and cooled.
Whole home
Five or more rooms, sized to replace the existing heating.
Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
Sevenoaks is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
The survey
On a survey in Sevenoaks the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
